The Royals (21-31, 14-14 Home) will go for the series win today when they host the Seattle Mariners (25-28, 11-13 AWAY) at Kaufman Stadium in Kansas City, MO. First Pitch is scheduled for 2:10 p.m. EST with coverage provided by MLB.TV.
Kansas City took Game 2 of the series on Saturday, 5-0. While the offense came alive for nine hits and five runs, the real story of the day is pitcher Stephen Kolek’s complete game shutout.
Kolek’s performance leaves some big shoes for Sunday’s starter, Seth Lugo, to fill. Lugo is 1-4 in ten starts with a 3.68 ERA and a 1.40 WHIP. This will be the second time he has faced the Mariners in Seattle this season. The first came on May 2; he pitched six innings, allowing eight hits, two earned runs, and two walks while striking out six.
Seattle will hand the ball to Bryan Woo to start the day. Woo has gone 4-2 this season in ten starts with a 3.51 ERA and a 0.98 WHIP. He faced the Royals at home earlier in the year, on May 1. He pitched six innings and allowed seven hits (including two home runs), and six earned runs in a no decision.

Our Kansas City Royals vs Seattle Mariners Prediction
I can’t see why the public is once again favoring the OVER for this matchup. Neither side has been great at the plate. With last night’s shutout, the Mariners have averaged under three runs per game over the last week and are hitting an MLB low of .148. Yes, Kansas City knocked in five runs yesterday, but they are still hitting just .215 over the last week. Factor in two solid pitchers getting the start, and you have a recipe for a low-scoring game.
Our Seattle vs. Kansas City Pick: UNDER 8.5
